Have We Sold Ourselves Out?
21 January 2015 | by HitchcocSee all my reviews

If energy is the key to everything, but the byproducts are so devastating. Tyson gives us the possibilities of dong something about this. Wind, water, solar, and conservation are the answer. We have everything we need, but it might involve some sacrifice. Yes, it is not cost effective in the short term. But will we be standing in a desert or a carbon dioxide infested orb, wondering what we have done. And it will be too late. People say Tyson is preachy and liberal and anti-business. Damn right because he knows from his incredible scientific knowledge, exactly what is happening to the world. Most of the world scientists are in agreement, but we tend to make it seem as if it's a 50/50 proposition. I don't think I'm comfortable taking my scientific advice from some windbag radio talk-show host. If you have watched the series, you know the magnificence of the universe. Enjoy it for now, because future generations probably won't get the chance.
